Encapsulation is, in some ways, the key to object-oriented programming Our objective should be to make each part as independent as possible from its peers Classes and methods should receive as much information as is necessary to perform their allotted tasks, which should be limited in scope and clearly identified The introduction of the private, protected, and public keywords have made encapsulation easier Encapsulation is also a state of mind, though PHP 4 provided no formal support for hiding data Privacy had to be signaled using documentation and naming conventions An underscore, for example, is a common way of signaling a private property: var $_touchezpas; Code had to be checked closely, of course, because privacy was not strictly enforced Interestingly, though, errors were rare, because the structure and style of the code made it pretty clear which properties wanted to be left alone.

Note The Interlocked class has been greatly expanded in 2.0. Some of the functionality I describe here

This extra stuff will not hurt your page, but it does make your page larger than it needs to be, thus increasing the transfer time across the Internet and the rendering time needed by your browser..

On 32-bit systems, the 64-bit (long) integer type is a double-precision type. This means that all reads and writes require a pair of instructions, and it is always possible that a thread switch between the first and second instruction could give you a scrambled value. In 2.0, the Interlocked class s expanded 64-bit support allows you to do all reads and writes through the Interlocked class e.g., long Local64 = Interlocked.Read(ref Variable64) and Interlocked.Exchange(ref Variable64, Local64) so that you can write double-precision code without having to use explicit locking. Never forget that (somewhat as with volatile variables) Interlocked only protects you if all access to a variable is through Interlocked.

By the same token, even in PHP 5, we could break the rules and discover the exact subtype of an object that we are using in a class-switching context simply by passing it to the get_class() method..

More sophisticated locking, at a noticeably higher cost The Monitor class will cover maybe 90% of your synchronization needs. Because using the Monitor class involves neither operating system calls nor finalizers, you should always make the Monitor class your default synchronization solution, only turning to WaitHandle descendants when you need to do cross-process (or cross-AppDomain) synchronization, or when the Wait/Pulse mechanism can t solve your signaling needs. The abstract WaitHandle class is a wrapper for operating system synchronization primitives. Its Mutex, AutoResetEvent, ManualResetEvent, and Semaphore descendants support different types of functionality, but all wrap OS handles: use WaitHandle objects within a using block where you can, and call Close where you can t automatically call IDispose.Dispose. (As with the GDI+

How significantly these issues affect you depends on your individual circumstances. Just be aware that this occurs.

function workWithProducts( ShopProduct $prod ) { if ( get_class( $prod ) == "cdproduct" ) { // do cd thing } else if ( get_class( $prod ) == "bookproduct" ) { // do book thing } } You may have a very good reason to do this, but in general, it carries a slightly uncertain odor. By querying the specific subtype in the example, we are setting up a dependency. While the specifics of the subtype were hidden by polymorphism, it would have been possible to have changed our ShopProduct inheritance hierarchy entirely with no ill effects. Our code ends that. Now, if we need to rationalize the CdProduct and BookProduct classes, we may cause unexpected side effects in the workWithProducts() method. There are two lessons to take away from this example. First, encapsulation helps you to create orthogonal code. Second, the extent to which encapsulation is enforceable is beside the point. Encapsulation is a technique that should be observed equally by classes and their clients.
